Import of 1.0.5 yields immediate SyntaxError

[mattghali]

Environment:

Python 3.5.4 (v3.5.4:3f56838976, Aug  7 2017, 12:56:33) 
[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin

Freshly installed aws_embedded_metrics-1.0.5-py3-none-any.whl via pip3 install --user aws-embedded-metrics

any import yields a SyntaxError exception:

Am I doing something wrong?

I suspect that this is actually a simple packaging error, with a missing Requires-Python attribute which would have signaled to my pip that our Python 3.5.4 was too old to handle the type annotations.

I suggest you require >= 3.6 in your packaging.
